The roof of my mouth near the back of my front teeth and then near a molar of mine has been feeling a little sore lately (and I keep rubbing it with my tongue so my tongue somewhat feels weird but I think its just the friction). There are no raised bumps or anything I can feel that I don't think is just my regular mouth structure. It's similar to the feeling you get when you burn the roof of your mouth. If I had given my boyfriend unprotected oral sex about 21 days ago, should I be concerned about STDs like herpes? I've had this feeling for a few days now and it's seriously worrying me. He has never had anything noticeable on his penis to raise suspicion that I have noticed. I posted this in the herpes forum as well, but then I had realized it was unmediated which makes me prefer to post here.
